2006 Mazak QTN 350-II CNC Turning Center

The Mazak Quick Turn Nexus 350-II x 80 is a long-bed heavy turning center from one of the most widely supported lathe platforms ever built, with a reputation for rigid, dependable shaft work that has made the QT Nexus series a staple in oilfield and energy machine shops. This 2006 machine swings 26.77 in over the bed, turns up to 16.50 in maximum diameter with a 10.39 in standard machining diameter, and carries a full 80 in between centers with an MT No. 5 tailstock for long workpiece support. The 4.4 in spindle bore passes 3.5 in bar through a 40 HP main spindle running to 3,300 RPM, and the 12-position drum turret indexes through heavy roughing and finishing passes alike. Mazatrol conversational programming gets shaft jobs from print to first cut quickly, with full G-code compatibility for programmed production work.

Compared with the first-generation Mazak Quick Turn Nexus 350, the -II generation stepped up to the Mazatrol Matrix control platform with faster processing and expanded conversational support, along with refinements in rigidity and thermal stability that hold tighter tolerances across long cuts. The 80 in bed configuration also extends well past the standard QTN 350 footprint, opening the envelope to the long shafts, mandrels, and downhole components that command premium rates. For a shop quoting long heavy turning, this QTN 350-II x 80 covers capacity that few machines in its class can reach.
